I was able to solve the first part of this problem pretty easily, but I have no idea how to approach part B. Can anyone assist with some guidance? (I'm not looking for an answer as I want to do that myself so I can learn the material). Thanks in advance.
Suppose that the resistance between the walls of a biological cell is 6.00 x 10^9 ohms.
A.) What is the current when the potential difference between the walls is 25 mV?
The answer to this 4.166x10^-12 Amperes.
B.) If the current is composed of Na+ ions (q = +e), how many such ions flow in 0.5 s?
I thought that maybe it had to do with the equation delta q= I(time), but I was apparently wrong.

I see no reason why it couldn't. q = N x e0 = I x t and
N = I x t / e0 = 1.3 x 10^7 ions
